Unknown (presumed dead)
- "Command HQ, this is Specialist Wilson. My team is gone - they're all dead. I'm running blind here, what are my orders? Over."
- ― Specialist Wilson [src]
Specialist Wilson was a Marine in Doom 3 heard over the radio during the Mars City Revisited level. He and his team were on patrol when the invasion occurred. The whole squad was killed except Wilson, who somehow managed to survive.
He can be heard reporting in to Sergeant Kelly, asking for orders. The Sergeant tells him to fortify his position and wait for help. The player does not hear him over the radio again. Wilson was most likely killed while trying to fortify or hold his position, given that the Protagonist is stated to be the only known survivor.
- Specialist Wilson is not encountered directly, but is most likely a technology or weapons specialist, possibly a demolitionist, heavy weapons operator, or similar.
- Possible factual error: Assuming that the fictional US Space Marine Corps uses the same ranking system as the real life US Marine Corps, then Wilson should be a Corporal, as the rank of Specialist is only used by the Army.
- During his radio transmission, the sound of a plasma gun being reloaded/charged can be heard at one point, pointing out that Wilson had access to superior tier of weaponry as opposed to regular security personnel.
- If this is true, then it's possible that his body could be at EnPro Plant in which there is a corpse of a marine with a plasma gun lying nearby.
